BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 354,226, dated December14, 1886.

Application filed July 24, 1886. Serial X0. 208.906.

My invention relates th that class of brick-,

machines'kuown as brick-repressing" machines, wherein it is desirable,after the bricks have been formed in the molds, to give them a secondand final pressure, by which any excess of moisture is removed, the airpressed out, and the bricks given their final set and shape, ready to beburned or baked in the kiln.

My invention has for its object the simplification of construction ofthis class of ma chines,as well as their increased efficiency; and itsnovelty will be herein set forth, and specifically pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of myimproved machine. Fig. 2 is a central sectional end elevation of thesame. Fig. 3 is an enlarged central section,in side elevation,of thecarrier, mold-box, and its movable bottom.

The same letters of reference are used to indicate identical parts inall the figures.

The framework of my machine is preferably composed of a single castingconsisting of an arch, A, and base or platform 13. This frame-work issupported at one end upon two wheels, 0, suitably j ournaled to theplatform, and by legs D at its opposite end.

Pivoted, as at a, to lugs upon the upper side of the platform are twolevers, E, to the upper end of which are pivoted two similar levers, F,the central pivots, b, of which two sets of levers are connected by across-tie bar, G, from which extends a pivoted link, H, whose outer endis pivoted, as at c, to an operating handlever, I. The upper ends of thelever F are pivoted, as atd, to lugs upon the bottom of a carrier, J,whose upwardly-extending sides are vertically planed to fit ways 6 uponguideribs K, extending from the inner side of the arch, as shown.

Upon the top of the carrier J is bolted the (No model.)

able construction, and in which the brick is pressed. Vithin this box isfitted a movable bottom, M, to the lower side of which, at the center,is secured a rod or leg, N, whose bottom is tapped to receive aset-screw, f, or any other suitable gaging device, which restsupon across-piece, g, secured upon uprights h, bolted or otherwise secured tothe platform.

To aid in guiding the leg N in a perfectly vertical position, aperforated arch, 2', is pro vided, through which the leg passes, andwhich is bolted to or may form a part of the crosspiece 9.

That part of the plate of the carrier J which would form the bottom ofthe compressbox is cut out with beveled edges, as shown in Fig.3,'thereby leaving the bottom M to rest upon the upper edge of saidcut-out portion, which edge or the under side of the bottom M isprovided with contact-lugs j, the purpose of which construction justdescribed is to enable any of the clay that may escape or be squeezedthrough the joints at the bottom to readily and easily escape and fallthrough the carrier.

Just over the open top of the compress-box is an adjustable platen, O,which fits around the top of the arch, is guided between ways 7c, and isprovided on its under side with a removable plate, P, shaped to fitsnugly in the top of the box.

A set-screw, R, engaging with a threaded perforation in the top of thearch, has its top passed through a cross-piece, S, bolted to theuprights of the platen, and is held from lon gitudinal displacement withreference to the platen by means of the collar m. By turning this screwR by means of anysuitable handle, T, the platen and its plate P can beadjusted up or down with reference to the arch and the compress-box, aswill be readily understood.

The adjustment of the parts is such that when the lever I is in anupright position the toggle-levers E F are so inclined as to bring thecarrier J and compress-box L to their lowest position, as shown in Fig.2. \Vhilc in this position, the top of the movable bottom M is on alevel with the top edges of the compress-box to receive the; brick Uwhich is to be pressed. The downstroke of the lever I, by causing thetogglelevers E F to assume a bottom M rests upon the carrier J, and pro:

ceed upward until the plates P of the platen enter the top of the boxand effects the pressure of the briclgwhich pressure is maintained equaland even on all sides, as will be readily understood. The return upwardstroke of the lever I lowers the carrier and compress-box until the legN, being arrested by the crosspiece stops the further movement of thebottom M, whereupon, the compress-box and carrier still furtherdescending, the brick is forced out of the box, as shown in Fig. 2, andis removed and replaced by a fresh brick to be pressed.

To prevent injury to the parts, spring-buffers may be employed, the one,a, surrounding the leg N, and the other, 0, Fig. 1, recessed in thearch. so as to receive the end-thrustof thetiebar G.

The pnrposepf the buffer a is to receive the blow and weight of thecarrier J in descending, and both of these springs n and 0, which arecompressed and under tensiorrwhen the machine is at rest, serve to aidthe operator in giving its initial start.

For convenience in transporting themachine from place to place, thelever I serves as a trundling-handle, which can be locked in ahorizontal position bya chain, V, or any other suitable means.

Of course it will be readily understood that both the bottom M and leg Nmay be lifted bodily out of the machine, to be replaced by a bottomhaving any design formed upon its upper side which it is desired tostamp or impress in the brick. The same is true of the platen P. The boxL is likewise removable, so that by having a number of suchinterchangeable parts the same machine will answer to press bricks ofany desired shape and embossed or ornamented in any desired manner.

WVhile I have illustrated the machine as a handmachine only, it isevident that power might be employed to operate it by connecting the rodH to a crank, wrist-pin, or cam.

Having thus fully described my invention, I claim- 1. In abriek-pressing machine, the combination, with a carrier operated bytoggle-levers, of a compress-box carried upon said carrier and providedwith a movable bottom and a platen arranged over said compress-box,substantially as described.

2. In a brick-pressing machine, the combination, with a carrier operatedby toggle-levers, of a compress-box carried upon said carrier andprovided with a movable bottom and an adjustable platen arranged oversaid oompress-box, substantially as described.

3. In a brick-pressing machine, the combination, with avertically-moving carrier and a compress-box supported on said carrier,of a movable bottom fitted in said compress-box.

and provided with a rod or leg extending down through said carrier and astop with which said leg engages to cause the expulsion of the brickafter the same has been pressed, substantially as described. r

4. In a brick-pressing machine, the combination, with avertically-moving carrier operated by toggle-levers and a compress-boxsupported on said carrier, of a movable bottom titted in saidcompress-box and provided with a rod or leg extending down through saidcarrier and a stop with which said leg engages to cause the expulsion ofthe brick after the same has been pressed, substantially as described.

5. In a brick-pressing machine, the combi nation, with avertically-moving carrier supporting the compress-box and operated bytoggle-levers, of spring-Lin fi'ers arranged to receive the downwardstroke of said carrier and toggle-levers, substantially as and for thepurpose described.

6. In a brick-pressing machine, the combination, with the compressboxprovided with a movable bottom, of a vertically-movable carrier uponwhich said compress-box is supported, said carrier having a cut-outportion immediately under said movable bottom, sub stantially as and forthe purpose described.

7. The combination, with the verticallyguided carrier J, of thetoggle-levers E F, tiebar G, link H, and operating-handle I, substantially as described.

8. The combination, with the arch A, of the vertically-adj ustableplaten O,removable plate P, and operating-screw R, substantially as andfor the purpose described.

9. The combination, with the compress-box L, ofthe movable bottom M,carrier J, leg N, set-screw f, and stop 9, substantially as described.

10. The combination, with the verticallyguided carrier J, toggle-leversEF, tie-bar G, link H, and operating-handle I, of thevertically-adjnstable platen O, removable plate P, and operatingscrew R,substantially as de scribed.
